Same 7+7 castellated 2.54-pitch footprint as [[amz-xiao-esp32c3]]. Sense expansion board snaps on via B2B connector (z 4.18-5.43); camera FPC connector overhangs the non-USB end, and the folded FPC loop + camera head overhang the USB end by up to 3.1 (bbox x to -3.11) - leave clearance above the USB in enclosures. Camera can be unfolded away from the board on its FPC.
ESP32-S3R8: 8MB PSRAM + 8MB flash, WiFi b/g/n + BLE5 via U.FL external antenna (included). Sense expansion: DVP camera + PDM digital mic + microSD. Camera per listing is OV2640 1600x1200, but Seeed discontinued OV2640 and ships OV3660 2048x1536 on newer builds - check the module marking on the physical unit.
High - official Seeed 3D model, rebased to standard frame with the original untouched in ref/. Note wiki quotes "21 x 17.8 x 15mm with expansion" vs 13.96 measured on the model (likely incl B2B seating tolerance) - trust the STEP for fits. Camera sensor variant (OV2640 vs OV3660) needs a physical check.
